OSCAR E. BROWN, OF BUFFALO, NEW' YORK.

HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 481,271, dated August23, 1892.

Application filed November 14:, 1891.

To all whom it may concern:

Be it known that I, OSCAR E. BROWN, a citizen of the United States,residing at Buffalo, 1n the county of Erie and State of New York, haveinvented new and useful Improvements in Horseshoes, of which thefollowing is a specification.

This invention relates to double or compound horseshoes, which consistof an upper shoe secured to the hoof of the animal and a lower auxiliaryshoe removably attached to the upper shoe.

The object of myinvention is the provision of a secure and reliable lockfor fastening the lower shoe to the upper shoe, which will permit thelower shoe to be readily applied to and removed from the upper shoeWhenever it becomes necessary to renew the lower shoe or resharpen itscalks.

My invention has the additional object to cushion the horseshoe, so asto reduce the force of its impact against the pavement and relieve theanimal of the stiff unyielding impact of ordinary shoes.

In the accompanying drawings, Figure l is a perspective of myim provedhorseshoe, showing the lower shoe secured to the upper shoe. Fig. 2 is asimilar view showing the lockinglevers swung outward to the position inwhich they permit the lower shoe to be detached from the upper shoe.Fig.3is alongitudinal section of the shoe in line cc, Fig. 1. Fig. 4. isa cross-section in line 'y y, Fig. l.

Like letters of reference refer to like parts in the several figures.

A represents the upper shoe, which is fastened to the hoof of the animalby nails in the usual manner, and B is the lower detachable shoe. Thelatter rests with its upper surface against the under side of the uppershoe and is provided at its toe with an abutment or upwardly-projectinghook h, which overlaps the adjacent portion of the upper shoe, so as tohold the front portion of the detachable shoe in place upon the uppershoe, the latter being provided at its toe with a recess which receivessaid hook.

C O are horizontal locking levers or latches attached to the heels orrear portions of the lower shoe and whereby the rear portions of thelatter are fastened to the upper shoe.

These locking-levers are provided at their in- Serial No. l11,921. (Nomodel.)

ner ends with vertical pivots d, which turn in openings formed in theheels of the lower shoe. The pivots d are preferably provided withexternal screw-threads d', and their openings are correspondinglythreaded, as shown in Fig. 4. This construction permits the pivots toturn freely and at the same time confines them in their openings withoutthe necessity of providing them with heads or similar retainingprojections, which would wear off in time and permit the pivots to leavetheir openings. The locking-levers when in their normal position overlapthe heels or rear portions of the upper shoe and are held in thisposition by a longitudinal screw or bolt E, attached to a cross-bar F,which connects the rear portions of the upper shoe. The outer bifurcatedends of the locking-levers straddle the bolt E and are held on the sameby the nut e of the bolt. The inner ends of these levers overlap eachother, and the nut e bears against the face of the outer lever, asshown. The inner portions of the locking-levers and the heels of theupper shoe are recessed at their contiguous portions, as shown at g, soas to render the upper surfaces of the locking-levers flush or nearlyflush with the upper surface of the fixed shoe. By thus recessing theheels of the upper shoe shoulders h are formed on the heels of the uppershoe, against which the adjacent lower sides of the lockinglevers abut.Upon tightening the nut of the bolt E the locking-levers are forcedinwardly toward the connecting-bar F, which action causes the levers tomove the lower shoe rearwardly on the upper shoe and draw the hook orabutment b of the lower shoe tightly against the toe of the upper shoe,the inner edges h of the shoulder h serving as fulcrums for the lever inclamping the hook against the upper shoe. The locking-levers thusperform the double function of holding the rear portions of the lowershoe against the upper shoe and moving the lower shoe lengthwise uponthe upper shoe for firmly clamping the hook b against the toe of theupper shoe. The lower shoe is readily detached from the upper shoe byremoving the screw-nut from the bolt E and swinging the locking-leversoutward so as to clear the heels of the upper shoe, as shown in Fig. 2,and then moving the lower shoe forward to disengage its hook from therecess of IOO the upper shoe. In applying the lower shoe its hook isfirst engaged with the recess of the upper shoe, and the locking-hooksare then swung inward over the heels of the upper shoe and clamped uponthe bolt E by the nut e.

I is a cushion interposed between the adjacent faces of the two shoesfor easing the blows or impact of the shoe against the pave ment andrelieving the legs of the animal. This cushion preferably consists of astrip of rubber, which is clamped between the two shoes.

The lower shoe is preferably provided with removable tapering calks,which are seated in upwardly-flaring openings in the lower shoe and areheld in said openings by the upper shoe. The upper shoe may be usedmerely as a support for the attachment of the lower shoe, so that onlythe lower shoe need be removed for resharpening its calls or removing itWhen worn out, or, if desired7 the upper shoe may be employed as asmooth shoe when the condition of the streets permits of such use andthe lower shoe be applied when a shoe with calks is required.

I claim as my inventionl. The combination, with the upper shoe, of thelower shoe provided at its toe portion with a hook interlocking with theadjacent portion of the upper shoe and at its rear end with a leverengaging with the rear end of the upper shoe, and a retaining device forlocking the lever in place, whereby the two parts of the shoe aresecurely fastened together, substantially as set forth.

2. The combination,\vith the upper shoe, of the lower shoe provided atits toe portion with a hook interlocking with the toe of the upper shoeand at its heel portions with locking-levers which overlap the heelsofthe upper shoe, and a retaining device whereby the levers are held intheir locked position, substantially as set forth.

3. The combination, with the upper shoe provided at its heel withshoulders, of the lower shoe provided at its toe portion with a hookinterlocking with the toe of the upper shoe and at its rear portionswith locklng-levers which overlap the heels of the upper shoe and bearagainst the shoulders thereof, substantially as set forth.

et. rlhe combination, with the upper shoe having a cross-bar connectingits rear pol'- tions,of alower shoe provided with alockinglever engagingwith a heel of the upper shoe,

and a retaining-bolt attached to said connecting-bar and having a nutwhereby the locking-lever is held upon the bolt, substantially as setforth.

5. The combination, with the upper shoe havingits heels provided withshoulders, of the lower shoe provided at its front portion with a hookengaging with the toe of the upper shoe and at its rear portions withlockinglevers overlapping the rear portions of the upper shoe andabutting against said shoulders, and a tightening-bolt arranged on theupper shoe and whereby the levers are held in their locked positions,substantially as set forth.
